HYDRANT.

Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed December 14, 1904. Serial No. 236,833.

To all whont it may concern.-

Be it known that I, VIRGIL H. MILLS, a citizen of the United States,residing at Hubbard, in the county of Hill and State of Texas, haveinvented certain new and useful Improvements in I-Iydrants, of which thefollowing is a specification.

This invention relates to the type of yardhydrants provided with a ventfor automatically draining the pipe to prevent freezing in cold weather,and has for its object to devise a novel joint or coupling means betweenthe spout or discharge-pipe and the plug of the cock, whereby ordinarypiping and a waste-cock may be employed.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means forefiecting the result reference is to be had to the following descriptionand accompanying drawings.

While the inventlon may be adapted to different forms and conditions bychanges in the structure and minor details without dearting from thespirit or essential features thereof, still the preferred embodimentthereof is shown in the accompanying drawings, in which Figure 1 is aview, partly in elevation and partly in section, of a hydrant embodyingthe invention. Fig. 2 is a transverse section of the waste-cock on theline w 20 of Fig. 1. Fig. 3 is a perspective view of the waste-cock.Fig. 4 is a section of the hydrant on the line y y of Fig. 1.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The waste-cock is of ordinary construction and comprises the casing 1and valveplug 2, the casing being provided with an end 3 for coupling tothe service-pipe 4. The plug 2 is limited in its movement by pin 5,projected laterally therefrom, and a pair of pins 6 ,extended upwardfrom the casing 1. In one position of the plug 2 its opening 7 registerswith the opening through the coupling end 3, and in another position theopening 7 registers with the waste 8, through which the Water standingin the hydrant drains.

The upper end of the plug 2 is provided with a recess 9 to receive thelower end of the discharge-pipe 10, the latter being connected theretoin any manner, so as to turn therewith and maintain a tight joint. Therecess 9 is in communication with the space 11, formed within the plug2, and with which the opening 7 communicates. In the preferableconstruction the recess 9 is of a size to receive approximately an inchand a uarter to an inch and a half pipe and sma ler, thereby makingprovision for coupling to the plug any size of pipe within certainlimits. Clampblocks 12 are provided at opposite sides of the recess 9and are held in place by guides 13, the latter being in the form ofboxes projected from the walls of the recess 9 and open upon their innersides to receive the blocks 12. Set screws 14, threaded into openings inthe upper portion of the plug 2, have their inner ends in engagementwith the blocks 12 to force the latter inward when it is required toclamp the pipe 10. To prevent slipping and to insure positive engagementbetween the blocks 12 and pipe 10, the inner or gripping faces of saidblocks are toothed or serrated. A reducer-fitting 16 is threaded to theupper end of the plug and its upper end recelves a packing-gland 17, bymeans of which a water-tight joint is maintained between the pipe 10 andthe fitting, so as to prevent possible leaking at the oint.

While the construction illustrated admits of the employment of differentstyles of pipe, and for this reason is preferred, nevertheless any meansmay be resorted to for coupling the pipe 10 to the plug 2 which willadmit of the employment of an ordinary waste-cock and water-pipe in theformation of a hydrant embodying the invention.

The bib or nozzle 18 at the end of the discharge-pipe 10 is connected tothe latter by a swivel-joint 19 of any type, whereby provision is hadfor turning said pipe 10 for opening and closing the hydrant Withoutchanging the position of the bib 18. A bracket 20 receives the bib 18and is connected to a stand 21, which may be a support of any kind,according to the make of hydrant. A handle 22 is secured to the upperportion of the pipe 10 for convenience of turning said pipe, accordingas it is required to open or close the hydrant.

Having thus described the invention,what is claimed as new is 1. In ahydrant, the combination of a waste-cock having a turn-plug providedwith a recess in its upper end in communication with the interior ofsaid plug, a pipe having its lower end inserted in said recess,clampblocks at opposite sides of the recess, set-- end inserted in saidrecess and held fast by the clamp-blocks, and means for maintaining atight joint between said pipe and plug, substantially as set forth.

In testimony whereof I afiiX my signature in presence of two witnesses.
